Designation:

OT-64

Info
Manufactured by: VOP-026 Sternberk, s.p.  
Type: Armoured Vehicles  
Name: Wheeled armoured personnel carrier  
 
 

The OT-64 (Obrneny Transporter) Armoured Personnel Carrier (APC) was jointly developed from 1959 by Czechoslovakia and Poland was used by them in place of the similar Russian BTR-60 (8 × 8) APC.

The vehicle, which uses many automotive components of the Tatra 813 series of 8 × 8 high-mobility trucks, entered service in 1964 and was subsequently widely exported.

The Polish designation for the vehicle is the Sredni Kolowy Opancerzny Transporter. Tatra of Czechoslovakia provided the chassis and automotive components and FSC/Lubin in Poland the armoured body and weapon system. Production of the OT-64 family was completed in 1990 after about 10,300 had been built for the home and export markets.

Although production of the OT-64 was completed many years ago the Czech Republic still has quantities of these vehicles available for export, see the OT-93 APC later on in this entry. Description

(OT-64C(1))

The hull of the OT-64 (8 × 8) APC is made of all-welded steel, with the crew compartment at the front, engine behind and the troop compartment at the very rear. This model has recently been called the OT-64A by the Czech Republic.

The driver is seated at the front of the vehicle on the left side with the commander to his right, both with a single-piece rear-opening door beside them. The driver has a single-piece hatch cover that opens to the rear and three day periscopes for vision to the front and sides. The commander has a single-piece hatch cover that opens forwards with a day periscope in its forward part, which can be traversed through 360. On the roof, between the driver's and commander's positions, is a searchlight which can be operated from inside the vehicle.

The Tatra 928-18 V-8 diesel engine is behind the commander and driver with the air inlet and outlets on the top of the hull and the exhaust pipes on either side of the hull.

The turret is in the centre of the vehicle and is mounted on an eight-sided plinth to enable the weapon to have some depression.

The troop compartment is at the rear of the vehicle and the troops enter and leave by two doors in the rear of the hull, each of which has a firing port. Over the top of the troop compartment are four roof hatches, each with a firing port, hinged on the outside. If required, the roof hatches can be locked vertical. There are two firing ports in each side of the troop compartment. The infantrymen are seated down each side of the vehicle on seats, which can be folded up to allow the vehicle to be used for cargo.

Steering is powered on the front four wheels and all eight tyres are provided with a tyre pressure regulation system, which allows the driver to adjust the tyre pressure to suit the type of ground being crossed. The vehicle is fully amphibious being propelled in the water by two propellers mounted at the rear of the hull. Before entering the water, a trim vane is erected at the front of the vehicle; when travelling, it is stowed on the glacis plate. Standard equipment on all vehicles includes an overpressure NBC system, a winch mounted at the front of the hull and bilge pumps.

A tow hook is provided at the front of the hull with a trailer coupling being provided at the rear. Maximum trailer weight is 3,000 kg, including payload.

The one-man manually operated turret is similar to those fitted to the Russian BRDM-2 (4 × 4) reconnaissance vehicle and BTR-60PB (8 × 8) APC and is armed with a 14.5 mm KPVT machine gun with a 7.62 mm PKT machine gun mounted to the right of the main armament and the sight to the left. The weapons have a maximum elevation of +29, depression of -4 and 360 turret traverse. Some models have been observed many years ago with a single Kolomna KBM 9K11 Malyutka (NATO AT-3 'Sagger') ATGW mounted on each side of the turret with lateral armour protection. Variants

In both former Czech and Polish service these vehicles are officially designated SKOT, SKOT-2, SKOT-2A and SKOT-2AP. The designations OT-64A, OT-64B, OT-64C(1) and OT-64C(2) are not always used. The Czech Republic has declared its vehicles under the CFE Treaty as being the OT-64, not SKOT, with the basic vehicle being the OT-64 and the model with the Russian type 7.62/12.7 mm machine gun turret being the OT-64A.

OT-64A (SKOT)

This is the basic member of the series. Some are unarmed while those used by Poland are fitted with a pintle-mounted 7.62 mm machine gun. There are five hatches over the troop compartment: two open to the left and right of the vehicle, the centre one opens forwards and the last two open to the left and right. All of them can be locked vertical. Some OT-64As have been observed with two Kolomna KBM 9K11 Malyutka (NATO AT-3 'Sagger') ATGWs mounted over the top of the troop compartment. Four Kolomna KBM 9K11 Malyutka (NATO AT-3 'Sagger') ATGWs are carried.

OT-64B (SKOT-2)

This model has only been used by Poland and has a square plinth with a pintle-mounted 7.62 mm or 12.7 mm machine gun. It has a shield that gives front and side protection to the gunner, but has an open top and is open at the rear. The OT-64B has three hatches over the troop compartment, the first one opens forwards and the other two open either side. This was probably a temporary expedient pending the delivery of turrets.

OT-64C(1) (SKOT-2A)

This is the model described in detail earlier.

OT-64C(2) (SKOT-2AP)

This is used only by Poland and is similar to the OT-64C(1) except that it has a new turret with a curved top. It is armed with a 14.5 mm KPVT machine gun with a 7.62 mm PKT machine gun mounted to the right of the main armament and the sight to the left. The weapons have a depression of -4 and an elevation of +89.5 which allows them to be used against helicopters and aircraft. Some vehicles have been observed with a single Kolomna KBM 9K11 Malyutka (NATO AT-3 'Sagger') ATGW mounted either side of the turret. This turret is also installed on the OT-62C tracked armoured personnel carrier.

The turret was developed by the WAT Military Technical Institute and is fitted with a CGS-90 sight.

OT-64C(1) with OT-62B turret

Morocco is known to have some OT-64C(1) (SKOT-2A) APCs with the original turret replaced by the same turret installed on the full tracked OT-62B.

DPT-64 repair

This is an OT-64 modified for use in the repair role. Its correct designation is the DTP-64 (Dilna Technike Pomoci) and it has two gas bottles on the roof.

OT-64 R-2M command

Former Czech command variant of the OT-64A. Polish Army designation for this model is the SKOT R-2AM with another variant being the SKOT R-2M. These are the OT-64A/SKOT-2A with periscopes and the eight-sided plinth, generator and antenna. All other R versions also have this plinth but without the armed turret.

OT-64/SKOT R-2AM command

This is an artillery command vehicle equipped with an R-130, two R-123Z and R-809 radios. This model can be identified by a collapsible Half Horse antenna on the right side of the roof, a generator on the rear deck and a telescopic antenna on the right rear.

OT-64 R-3MT radio

Former Czech version of the OT-64 with radio equipment. Polish Army designation for this model is the SKOT R-3M. These are also command vehicles and are similar to the R-2AM, but with the telescopic antenna on the left side of the hull.

Communications equipment includes an R-130, two R-123Z, an R-111, an R-405PT-1, an R-126, a K-1 and a K-2.

SKOT R-3Z command

This command vehicle is similar to the R-2AM but with a telescopic antenna on the left and right rear.

OT-64 R-4MT radio

Former Czech version of the OT-64 with radio equipment. It is identified by a sword antenna on the front side of the plinth and has an additional door in the left side of the hull, behind the exhaust pipe. No frame type antenna is fitted.

OT-64 R-4T command

This is an unknown Czech command version.

SKOT-R4 command

This command vehicle is similar to the R-3Z but can be identified by a sword antenna and a generator to the immediate rear of the plinth.

SKOT R-6 command

This is an air defence artillery command vehicle with the same mission as the Russian BTR-60Pu-12. It has no frame antenna but two telescopic antennas.

SKOT S-260 engineer

This is an engineer vehicle based on the basic SKOT and can be identified by grab handles over the rear engine deck and another two behind the exhaust pipes. These bars are believed to be fitted to avoid mine clearance hoses being ignited by the heat of the engine.

SKOT propaganda

This version has been declared under the CFE Treaty and is believed to be fitted with loudspeakers.

OT-93 APC

More recently a new version of the SKOT (8 × 8) APC, called the OT-93, has been developed and this is now being offered for the export market.

The OT-63 is basically the SKOT-2A with the original one-person turret armed with a 14.5 mm KPVT and 7.62 mm PKT machine gun removed and replaced by a turret armed with a single 7.62 mm UK-59T machine gun.

Turret traverse is 360 with weapon elevation from -5 to +80. Turret traverse and weapon elevation is manual.

This turret is the same as that fitted to the OT-65A (4 × 4) reconnaissance vehicle and the OT-62B full-tracked APC.

With the downsizing of the Czech Republic Army, quantities of OT-64 vehicles are now surplus to requirement and are being offered on the export market in a number of configurations.

As well as the OT-93, other versions of the OT-64 vehicle are being offered including police, firefighting, recovery/repair and bullion carrier.

PCO upgrade package for SKOT APC

The Polish-based company of PCO (Przemyslowe Centrum Optyki) is now offering a complete electro-optical upgrade suite for the SKOT (8 × 8) Armoured Personnel Carrier (APC). These PCO systems are of the Image Intensification (II) type.

The driver is seated at the front of the vehicle on the left side. PCO is offering two alternatives, the PNS-1 driver's night-vision goggles and the PNK-55 night-vision periscope.

The PNS-1 night-vision goggles are typically attached to the driver's head using a harness and have a magnification of ×1 and a minimum field of view of 38.

The PNK-55 night-vision periscope is a direct replacement for the day periscope and has a magnification of ×1 and a 30 field of a view and requires an 18-30 V DC power supply. It has an effective range of about 300 m compared to the 100 m of the original equipment.

The commander is seated to the right of the driver and PCO is offering two solutions. First is the TKN-1Z passive night-vision periscope with a magnification of ×3 and a 10 field of view.

Second is the more sophisticated modernised TKN-3Z periscope that has two channels, day and night. The day channel magnification of ×4.75 and a 9 30' field of view while the night channel has magnification of ×4.2 and a 11 30' field of view. In the night mode these have a maximum range of 1,100 m compared to 400 m of the first generation system.

Some versions of the SKOT are fitted with a one-person turret armed with a 14.5 mm KPVT and one 7.62 mm PKT machine gun. This turret is identical to that installed on a number of other AFVs, such as the Russian BRDM-2 (4 × 4) scout car which is still widely deployed around the world.

For this version of the SKOT, PCO is offering its CDN-1 periscopic day/night sight. The day and night channels have a magnification of ×3.7 and a 10.5 field of view, with an 18-30 V DC power supply required.

SKOT-2A minus turret

In Bosnia, a number of SKOT-2A vehicles were observed. These had their turrets removed and plated over and a simple cupola with a rear-opening hatch cover fitted. On the forward part of this cupola is a 12.7 mm machine gun in an unprotected mount.

WPT armoured repair and maintenance vehicle

Repair and maintenance version of the OT-64 that is fitted with a light crane for changing components in the field. Armament consists of a 7.62 mm PKT machine gun. It is fitted with an A-frame and is also referred to as the SKOT WPT.
